I still prefer the E53, E70 is nice but I think it looks too much like a version of the X3 without a squished hood (they're too similar now.) E53 still looks like an SUV (sav, whatever) whereas the E70 looks like it's trying to be a crossover SUV/Minivan.
But hey, I'd still drive one when the E53 is being worked on if someone wants to give me one.
